Description

Technical Field

[0001] The utility model relates to the technical field of cages, in particular to an anti-deformation and impact-resistant engineering plastic cage. Background Art

[0002] Engineering plastic cages are usually made of glass fiber reinforced polyamide 66 (GRPA66-25) and other materials. They are suitable for occasions that require lightweight, corrosion resistance and wear resistance. Compared with metals, they have the advantages of light weight, low density, friction resistance, corrosion resistance, good elasticity and good sliding properties, many of which are not available in metal cages.

[0003] However, compared with metal cages, its compressive strength may not be as good as that of metal cages. Therefore, under high load or high impact conditions, the current engineering plastic cage will be deformed, and the overall structural stability needs to be improved. Therefore, we propose an anti-deformation and impact-resistant engineering plastic cage. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, but compared with metal cages, its compressive strength may not be as good as that of metal cages. Therefore, under high load or high impact conditions, the current engineering plastic cage will be deformed, and the overall structural stability needs to be improved.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A deformation-resistant and impact-resistant engineering plastic retainer includes an injection-molded retainer body, wherein the retainer body is composed of two annular disks and a spacer column surrounding the two annular disks and serving as a connection. The outer sides of the annular disks are provided with an annular groove, and the centers of the spacer columns are injection-molded with a support channel. Reinforcement rings are clamped in the annular grooves on both sides, and an inner connecting column is provided in the corresponding support channel of the reinforcement ring on one side. The other end of the inner connecting column extends to the corresponding mounting hole through the reinforcement ring on the other side, and the inner connecting column is docked with the mounting hole through a clamping assembly.

[0007] Furthermore, corresponding sides between adjacent spacer columns are integrally formed with mounting cavities adapted for the balls / balls.

[0008] Furthermore, the thickness of the annular groove is half the thickness of the annular disk.

[0009] Furthermore, the supporting channel is circular and passes through the annular disks at both ends and is connected to the annular groove.

[0010] Furthermore, the reinforcement ring is made of metal.

[0011] Furthermore, the number of the spacer columns, support channels, inner connecting columns and mounting holes is the same, and the support channels are adapted to the inner connecting columns.

[0012] Furthermore, the clamping assembly includes an outer annular embedded groove provided on the periphery of the inner connecting column corresponding to the mounting hole, and a tightening ring is provided in the mounting hole corresponding to the outer annular embedded groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By opening an annular groove on the outer side of the annular disc and clamping a reinforcement ring in the annular groove, the structural strength of the retainer body is strengthened, making the overall structure more stable and effectively resisting deformation problems caused by high loads or high impacts. The embedded design of the metal reinforcement ring significantly improves the compressive strength of the retainer, making it perform better in certain application scenarios requiring high-strength support, without affecting the advantages of changing to engineering plastics (except for the increase in weight).

[0015] 2. The design of the internal connecting column and the mounting hole realizes a stable connection between the reinforcing rings through the snap-on assembly. This design not only enhances the integrity of the cage but also simplifies the installation assembly.

[0016] In summary, the present invention effectively solves the deformation problem of existing engineering plastic cages that may occur under high load or high impact conditions through innovative structural design and material selection, while improving the overall structural stability and compressive strength.

[0030] Example 1

[0031] like Figure 1-3 As shown, the utility model provides a technical solution: an anti-deformation and impact-resistant engineering plastic retainer, including an injection-molded retainer body 1, the retainer body 1 is composed of two annular disks 11 and a spacer column 12 surrounding the two annular disks 11 to serve as a connection, the spacer column 12 and the annular disk 11 are injection-molded as one piece, and are designed according to requirements. The corresponding sides between adjacent spacer columns 12 are integrally formed with an installation cavity 13 for adapting to balls / balls, which meets the basic functional requirements of the retainer.

[0032] Based on the above-mentioned retainer body 1, an annular groove 2 is provided on the outer side of the annular disk 11. The thickness of the annular groove 2 is one-half of the thickness of the annular disk 11, which does not affect the structure of the retainer itself. A support channel 3 is injection-molded at the center of the spacer column 12. The support channel 3 is circular and passes through the annular disks 11 at both ends and is connected to the annular groove 2. Reinforcement rings 4 are clamped in the annular grooves 2 on both sides. An internal connecting column 5 is provided corresponding to the support channel 3 on one side of the reinforcement ring 4. The end face of the internal connecting column 5 is circular, and the other end of the internal connecting column 5 extends to the mounting hole 6 corresponding to the penetration opening on the reinforcement ring 4 on the other side. The internal connecting column 5 and the mounting hole 6 are docked through a clamping assembly.

[0033] The clamping assembly includes an outer annular recessed groove 51 formed around the outer periphery of the inner connecting post 5, corresponding to the mounting hole 6. A tightening ring 61 is provided within the mounting hole 6, corresponding to the outer annular recessed groove 51. To dock the reinforcement rings 4 at both ends, first align the reinforcement ring 4 with the inner connecting post 5 and the annular groove 2. The inner connecting post 5 is positioned in the support channel 3, with the other end of the inner connecting post 5 extending into the annular groove 2 at the other end. The retainer body 1 is then flipped over, and the reinforcement ring 4 with the mounting hole 6 is docked with the inner connecting post 5. After the initial docking, the tightening ring 61 blocks the connection. Using a tool (hammer, press), the inner connecting post 5 is forced through the tightening ring 61, engaging the outer annular recessed groove 51 and the tightening ring 61, completing the docking of the reinforcement rings 4 at both ends.

[0034] It should be added that the internal connecting column 5 and the reinforcement ring 4 are made of metal, and the tightening ring 61 is made of vulcanized silicone rubber, so that the internal connecting column 5 can pass through and the tightening ring 61 can shrink to provide its entry. At the same time, it also has a certain hardness to ensure the stability of the clip-on installation.

[0035] like Figure 2 and 3 As shown, the number of the spacer columns 12 , the supporting channels 3 , the inner connecting columns 5 and the mounting holes 6 is the same, and the supporting channels 3 are adapted to the inner connecting columns 5 .

[0036] When the fixing plate 1 is tightened, the fixing plate 1 is tightened, and the fixing plate 1 is tightened to the groove 21 at the other end.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
